Vehicle seat

Abstract

A vehicle seat mounted with an occupant restraint device, the vehicle seat includes: a seat cushion frame; a seatback frame including a seatback side frame extending in a seat vertical direction at a seat width direction end portion of the seatback frame, the seatback frame being swingable at a seat rear end side of the seat cushion frame, and the seatback frame extending from the seat rear end side toward a seat upper side; a metal inflating body disposed along the seatback side frame, and configured so as to be stretched out toward a seat lower side such that a lower end of the metal inflating body abuts a vehicle floor surface; and a drive member configured to stretch out the metal inflating body in a case in which a vehicle collision at a seat front side occurs or the vehicle collision at the seat front side has been predicted.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 USC 119 from Japanese Patent Application No. 2018-6569 filed Jan. 18, 2018, the disclosure of which is incorporated by reference herein in its entirety.BACKGROUNDTechnical Field[0002]The present disclosure relates to a vehicle seat.Related Art[0003]The development of self-driving vehicles has been progressing in recent times. Such self-driving vehicles do not require a driver to sit in a vehicle seat facing the vehicle front during self-driving, allowing greater movement of vehicle seats and rotation of vehicle seats so as to face toward the vehicle rear to enable conversation with an occupant in a rear seat, for example.[0004]In such cases, occupant restraint devices such as seatbelts are provided at vehicle seats to allow greater movement of vehicle seats than in existing vehicles, and to allow rotation and so on of vehicle seats in plan view.[0005]Namely, vehicle seats are being provided with a ...

AI Technical Summary

Benefits of technology

The solution effectively prevents or suppresses seatback collapse by increasing the contact surface area with the vehicle floor, enhancing the seat's rigidity during frontal and side-on collisions while maintaining a compact and lightweight design.

Problems solved by technology

However, mounting a restraint device to a vehicle seat results in a large impact load being input to the vehicle seat through the restraint device by an occupant who moves under inertia in a collision.

Reinforcing a seat frame and the like of the vehicle seat in order to secure seat rigidity has the disadvantage of increasing the mass of the vehicle seat.
